GLASS-HOUSE POT.

SPECIFICATION forming part of Letters Patent No. 233,904, dated November2, 1880.

Application filed September 9, 1880. (No model.)

To all whom it may concern:

Be it known that I, GEORGE ZTMMERMAN, of Steubenville, county ofJefferson, State of Ohio, have invented or discovered a new and usefulImprovement in Glass House Pots 5 and I do hereby declare the followingto be a full,clear, concise, and eXactdeseription thereof, referencebeing had to the accompanying drawings, making a part of thisspecification, in which-like letters indicating like parts- Figure l isa perspective view of my improved glass-house pot, and Fi g. 2 isasectional .plan view, illustrative of the arrangement of my improvedpot with relation to the furnacewall.

Glass-house pots have heretofore been made with a single mouth orworking-hole opening into the chamber or compartment for melted glass,at which mouth or opening but a limited number of workmen or shops couldbe accommodated; also, in some cases, two mouths or openings have beenmade, one directly under the other, so that as theglass was lowered orpartly worked out of the pot the lower mouth could be opened for thepurpose of working out the balance of the glass with greater facility;but in all such eases only a single set of workmen could be employed atone time, and the quantity of glass which these few workmen or shopscould work cut has constituted a practical limit on the size or capacityof the pots employed in a glass-house. It is desirable, however,especially since the introduction of improved furnaces of increasedcapacity for melting glass, to increase the size of the pots, and inorder that this maybe done and still work out all the glass in therequired time, I have devised a pot, as at A in the drawings, havingtherein a single chamber, B, for holding the melted glass, with twomouths or openings, C, into such chamber. These openings, separatelyconsidered, may be of the usual or any desired form, but they arearranged in a common horizontal plane near the top of the pot, and areseparated a considerable space, so as to bring them near to the frontside angles of the pot, and thereby afford room for the passage ofafurnace escapeiue, E, between the mouths, if desired, and also room forseparate sets of workmen to operate at each mouth or opening at the sametime. In order to bring these two mouths into proper position withrelation to the furnacewall I hatten somewhat the breast a of the pot,so as to widen it and bring the front corners near to the wall; and Ialso prefer to make the openings G and side walls, b, of the pot in, ornearly in, a radial direction with reference to the furnace, so as toeconomize space and enable the different workmen to gather the glassfrom different sides or parts of the pot and not interfere with eachother.

Vith a pot thus made double the quantity of glass can be worked out in agiven time as compared with a pot having but one mouth. or at which buta single set of men can work.

The advantages resulting from my improvement a-re very important,especially in largesize furnaces, since the inability to work out morethan a certain limited quantity of glass from a single opening has beena serious difculty in the way of introducing the improved furnaces oflarge melting capacity into general use.

I am aware that double pots have been made having a separate mouth oropening for each compartment or division, one mouth opening into thecharging-chamber and one into the chamber containing the melted glass;but such a pot does not embody my invention, since, so far as workingout the melted glass is concerned, it has but one working-opening, andpossesses no advantage over the ordinary form of pot. V

By still further increasing the size or width of thc breast of the potthree or more openings or mouths may be made, substantially in themanner which I have above described.

I claim herein as my invention- A glass-house pot having a plurality ofmouths opening into the molten-glass compartm ent, said mouths beingarranged in a common horizontal plane near the top of the pot,substantially as described, whereby separate sets of workmen are enabledto work from the same pot through the different mouths at the same time.

In testimony whereof lI have hereunto set my hand.

GEORGE ZIMMERMAN.
